DEVICE AND A METHOD OF SENSING CHARACTERISTICS OF A FOOD MATERIAL AND A MACHINE AND A METHOD OF BREWING COFFEE

摘要

A device and a method of sensing characteristics of a food material and a machine and a method of brewing coffee. The device comprises: a wave source (20) configured for emitting waves to said food material (22), with the wavelength range of said waves comprising a selected near infrared band neighboring a visible band; a detector (26), configured for detecting intensities of the waves reflected by said food material; and an analysis module (28), configured for determining said characteristics according to the detected intensity of the reflected waves. Preferably, the food material comprises coffee powder, and the characteristics comprise at least any one of: color of the coffee powder (corresponding to the roasting degree of coffee powder); and grind fineness of the coffee powder.

主权项

1. A device of sensing at least any one of roasting degree of coffee powder and grind fineness of coffee powder, comprising:
a wave source configured for emitting waves to said coffee powder, the wavelength range of said waves comprising at least part of visible band and a selected near infrared band neighboring the visible band; a detector, configured for detecting intensities of the waves reflected from said coffee powder; and an analysis module, configured for determining said roasting degree of coffee powder and/or said grind fineness of coffee powder according to the detected intensities of the reflected waves.
